YTo azlwhoqit tt-mdyhonccr Be it known'that I",- JosErr-Ii ScHNrIAN,

a. citizen. of thejUn-ted States, residing at- Pittsbnrgh, the county' of vAllegheny and State of Pennsylvania, have invented new and ji p proveniente `CoalCar Wheels and of Whichtthe -iollowing is a Specification tion, whereby-'the constant' vWearing 'ofi they ordinary axleiwill' be obviateda view in elevation of one end der 4 at each end of -AnOtherobect 'of thei invention is'toI so construct the. device that. itfmay be vapplied brought out in connection with the following specification.

-Referring to 'the drawing, 4Figure 1 is a shovvingthe' rails, one' wheel,"and one end of the 'axle in vertical section; Fig. 2v is a view in end elevationof a .Wheel andend O the of a. coal car- Wheel is in place, 'a cap'17 is secured to the axle'with the Wheel capremoved; Fig'. 3V 'is a view partly in elevation and partly in vertical section of a modied form of the invention; and Fig. 4 is a perspective vievv of the bearingspacer. t

Reference character 1 designates the car body which is mounted en the 'usual axle 2 having Spindle ends 3, a shoulder 4 being rovided at the inner endV of e'ach spindle 3. n axles novvin use, the Wheels are journaled directly upon these spindle ends, resulting in a Wearing away thereof. Vith the present invention, abearing spacer 5 1s placed on these spindle ends, either -of a new -or used axle. This bearing spacer is cornposed of a cylindrical member 6 having an axial bore 7 to receive the spindle 3, and at the inner end-of each. spacer. is a disk-like collar 8 which engages withthe said' shoulthe axle. The bearing spacerl 5 is secured in place on the spindle 3 by means of in m eans. n

5 designated b y numeral 11.

Cylindrical roller bearings 12 -are mounted the periphery of the cylindrical pora cotterpin 9, or similar securspacer, 6

outer ends of the roller bearings.

The lnnerfends of the* roller 'bearin'gsfli enter the 'said sockets 1-1 in the outer acejof the disklike portion 8'. The sockets l1 'asl- -slst the ,grooves' 10 in retaining the-'roller vbearings in place and arcof greatvaiue in .v

'assembling' as they 4irmly hold the: inner ends of4 the, rollers against ldisplacement of suitable formation, maybe rebored to,

While thewh'eelis being-putin place'there-- over.. Thev Wheel 15 is provided with a' vlarger bore tha'n'usual, and int-nis connecsuitable size to permit its being placed over I the roller bearingsl ,The wall-of the wheel bore is indicated by vnumeral 16. When the 'it Will'benoted' that the cap 17'ccnsists 'of a cup-'shaped central portion 19 anda surrounding' flange 20. The cupfshaped portion 19incloses the -spindlegend and itsA Cotter pin 9 and -prevents displacement of the. -latter, Whilethe iange 20 engages with -the Hence it will be noted that the thrust of the roller hearings is taken up by the cap liange 20 and the ends of the' sockets 11.

For the purpose of lubricating the parts,

the spacer 5 is 'provided With'a circumfer ential'groove'22 which intersects' each of the ribs 14: so as to carry the lubricant from one roller bearing'to the other throughout the series, andl for supplying lubricant to this groove 22 a feed -port 24 is provided in the wheel hub. The lubricant in large quantity is contained in a chamber 25 in' the wheel` chamber 25 may be extendedentirely around the wheel between its hub and rim.

In the modied form, numeral nates the car body, 2 the axle, 3 the spindle, 4: the axle shoulder, 5 the bearing the cylindrical portion thereof, 7 the bore for thespin'dle, and- 8 the disklike end portion" of the spacer. The grooves 10 preferred port 24 form, likewise the oil lfeeding The Wheel 1 5 and the rollers 12 are also the same as in the preferred form. In'

this instance,- the bearing spacer and spindle are providedwith key Ways which receive a key 4or pin 27 to prevent rotation l 1 desigand recesses 11 are as in thev and the oil 'feeding groove 22',

web, and if desired, this pocket orof the bearing spacer, and a cap 28 is placed over the end of.-the'..s indie and held -in other form incloscs the .end of the spindle and prevents displacementof vtlie ctter pin 2 8', which lattenis the same as the one 9 of the .preferred form. i; 't'4 vvill be clear. that axle "has becoxneworn, a bearing) spacer as in the present invention mayv e a plied theretqand roller .bearings placed t erein to afford a. n ev'v4 bearin for either a new Wheel or a` rebored .ol ,Wheel. Also, it ivill be noted, vthat the roller bearings may befreai replaced when worn by merely taking o theciips and slipping out the old and inserting endwise a new roller, without havin to 'jack up/the car or to remove the wf eel. Owing to the large I"chamber tforholding the lubricant, it will be l'apparent .that the carma)y be run for a great ength of time before 1t becomes nec- .es's'ar to re lenish the supply of lubricant 4at; is caiined is: l 1.
